CHURN.

SPECIFICATION forming part of Letters Patent No. 225,832, dated March23, 1880. Application filed August 6, 1879.

To all whom it may concern:

Be it known that I, JOSEPH D. HoBBs, of Burlington, Des Moines county,Iowa, have invented a new and useful Improvement in Chorus, of which thefollowing is a specification, in which reference is made to theaccompanying drawings, showing, ll]- Figure 1, a top View; in Fig. 2, asection on the line at 00, Fig. 1; and in Fig. 3, a detail view of theventilator.

My invention relates to churns wherein the dashers are made toreciprocate by means of levers connected to shafts to which the dashersare attached; and my invention consists in combining with a churn-bodyhaving inner rounded corners to facilitate cleansing a pair of verticalrock-shafts carrying a series of dashers or paddles, cranks to operatethe rod, and a pivoted equalizer having slots in which pins attached tothe cranks play, the churn being constructed, arranged, and operated asmore fully hereinafter explained.

The drawings represent a square churn, with its box or body of wood,with four legs, N N N N, one on each corner, which legs begin at the topof the churn-box and extend a short distance below it, thus forming theinside concave corners, O O O O, of the churn. The four sides-of thechurn-box are bolted into grooves in the legs N, 850., by eight longbolts running entirely through the box and fastened at the ends byburrs-four bolts at the top of the box and four at the bot-tom. Withinthe churn are two dashers, A A,joined to the shafts B B. These dashers AA extend about two-thirds across the churn from opposite corners wherethe loose shafts B B are placed.

These dashers are cut into saw-teeth nearly the entire length of thedashers, and are in height about equal to one-half the height of thechurnbox. These shafts B B work on gudgeons on the lid from the shaftsare ventilators K K. In the center of the lid is a gudgeon, on whichworks a metal equalizer, M, in each end of which is a short slot, L L,in which work gudgeons E E of the levers or cranks D D. These levers orcranks have at one end a short slot, F F, which fits over the hooks G Oof the shafts B B. These levers are worked by handles G G.

The churn operates as follows: Put the gudgeons of the shafts B B on thegudgeonblocks on bottom of the churn; set the lid over the churn,putting the shafts B B through the wooden boxings H H; put the slots F Fof the levers or cranks D D over the hooks O O on the shafts B B; lowerthe levers till the gudgeons E E pass into slots L L at each end of theequalizer M. By working the levers or cranks D D backward and forwardthe shafts B B, to which the dashers A A are attached, move back andforth horizontally across the churn.

The churn may be taken apart, tightened, or loosened by properlyadjusting the bolts.

I am aware of the patent granted D. D. Frankfoder, March 21, 1871, inwhich are shown dashers attached to rock-shafts and operated by a seriesof connecting-levers; and I do not claim the invention shown therein, mydevice possessing the advantages of greater simplicity of construction,whereby it may not only be operated with greater case but manufacturedat less expense. Therefore What I claim is- In a churn having innerrounded corners for the purpose described, the combination of the shaftsB B, the cranks D D, having pins, and the centrally-pivoted equalizer M,slotted longitudinally on each side of the center pivot, whereby thealternate reciprocation of the cranks operates the dashers,substantially as described and shown.
